Zin is a teenager who gets into the most vital situations, often leaving ironic remarks or joking about how he hates himself. He presents his whole pessimistic attitude as a joke, both on himself and on others. His friends are Jimin and Lee, he can hardly call the second one that, since he always suffers ridicule and mockery from him, only sometimes responding in kind. Zin is complexed and his self-confidence appears only when he is alone with himself.
